| Abstract: |
| A study was conducted to seek the effects of different irrigation amount on shape index,physiological indexes and photosynthetic physiological indexes of muskmelon plants.The experimental material was Yipintianxia 208 muskmelon in greenhouse and water surface evaporation(Epan) was measured by a standard 0.2 m diameter pan used for irrigation control.Different kp crop-pan coefficients(Kp=0.45,0.60,0.75 and 0.90) were set up for water treatments.Through analyzing plant height,stem diameter,biomass,root/shoot,chlorophyll content,the results indicated that keeping the crop-pan coefficient (Kp) as 0.6 was more suitable than other treatments to the development of drip-irrigated muskmelon under mulch film in greenhouse.The muskmelon cell concentration demonstrated single-peak curve which was shown as T1>T2>T3>T4 under different Kp crop-pan coefficient water treatments.Water-saving and efficient management was reached in the treatment of T2. The temperature change law was the same inside and outside greenhouse during muskmelon growing period,indicating that greenhouse had good effect of heat preservation,which could guarantee normal growth of muskmelon crops. |
